To all whoin it may concern:

Be it known that we, Gnonen .E. Pn'r'rr, a citizen of the United States, residing at Memphis, Shelby county, and State of Tennessee, and HARRY, LANG, a citizenv of the United States, residing at Memphis, Shelby county, and State of Tennessee, have invented and discovered certain new and useful Improvements in Fuel- Oil Co'mpounds, of which the following is a specificatio In the operation of internal combustion engines two serious troubles are recognized by mechanics one, incomplete lubrication of the upperends of the cylinder chambers, resulting in'more or less friction and wear,

'and the other, incomplete combustion of all the fuel oil in the time between the strokes of the piston, resulting in carbon deposits with consequent troubles. The common lubricating system employed comprises a crank case partly fille with oil through which the crank revolves and splashes the oil up against the piston head and into'the lower open end of the cylinder chamber. These parts are thus thoroughly lubricated. The upper part of the chamber and the parts connected therewith, however, only receive such lubrication as results from thesmall quantity of oilworkin cits-way past the piston. As the piston pac ing rlngs are constructed to fit tightly it follows, as a matter of course, that but only the minutest' quantity of oil can pass them and reach said upper chamber. Therefore, during each stroke of the piston the piston rings glide over a well oiled surface during a part of their course of travel but durin the remainder of the stroke are in'friotlo'nal contact with a comparatively dry and poorly lubricated surface, which resists their free movement. This not only makes the stroke of the piston through the upper part of the c linder more difficult, resulting in a con-' siderable waste of power, but in addition, this friction causes overheatln of the motor, which interferes with its e ective operation and reduces its wearing and resisting qualities. The incomplete combustion results in'carbon deposits, forming a semi-- crystalline substance which accumulates onthe piston heads, valves, spark plugs and upper cylinder walls, and causes many of the troubles experienced in the operation of the llhe purpose of our sald invention 18 to provide a compound which may be introduced into the fuel oil (gasolene' or other fuel oil) in proper proportion and will properly difi'use through said fuel oil in mmute but uniform quantities, which composition is comprised of lubricating and carbon solvent elements, to the end that vthe troubles above referred to are overcome.

The accompanying drawing is illustrative only, and intended to show, in section an in ternal combustion engine of a common type,

Figure 1 showing the pistonon compression stroke, and Fig. 2 on exhaust stroke, to

.make more clear an understanding of the use of our said invention, and to make clear the parts referred to when the upper and lower ends of the cylinder are referred to herein. The movement of the crank 1 causes oil to splash into the lower part A of the c linder up, to about point 2, the portion B.

a ove point 2 receiving almost no lubrica- I tion. By our invention lubricating oil mixed with fuel enters at 3 imparting lubrication to the Walls B and the piston head, and also aids in the prevention of incrustation of carbon on the cylinderwalls.

The composition consists of-- Oil petrolatum, refined, neutral,

Carbon tetrachlorid 246 Nitro-benzol It will be understood that theseproportions may be varied without departingfrom our said invention, the proportions above defined being those that have been found to produce the most perfect composition for V the purpose desired. For instance, the proortion of oil petrolatum-may vary between $25 and 775 parts and the carbon tetrachlor'id between 225 and 27 5 parts or even through a wider range within our invention.

The said substances are thoroughly com- 'bined and'mixed together, and put up in cans or bottles containing given quantities, such as w1l1 make packages of a convenient size for handling, and for use in connection with the operation of automobiles, motor inder through the intake, manifold, as the gasolene itself is drawn in.

burned before the petrolatum is materially affected by the heat. This difference, between the hysical properties of the two elements ena les the petrolatum to remain in the combustion chamber in the upper end of the cylinder, above the pistons, and act as a asolene is burned in the usual way. This li ibrication reduces the friction, diminishes the wear on the parts, and produces all the good elfects due to the thorough lubrication of these and associated parts at the upper end of the cylinder.

The carbon tetrachlorid is non-combustible and a carbon solvent and serves to disintegrate the carbon and causes the removal of any that may have accumulated on the cylinder heads, walls, valves and spark plugs, and after the parts are once cleaned, maintains said parts ina clean condition. The carbon tetrachlorid being non-combustible, will remain in the cylinder as such even after the explosion and thus its action on the carbon deposits will take place fora longer-period thanif it were consumed by the explosion. f

The nitro-benzol is a deodorant and at the same time an odorant. nothing to the intrinsic value of the composition, and may be omitted if desired, it is useful asa flavoring for the composition and'also acts to conceal to a certain degree the carbon tetrachlorid.

The tetrachlorid remains in the cylinder in the form of a vapor and under the pressure existing therein will penetrate and soften any carbon which may be on the parts of the upper end of the cylinder chamber,

resulting in such carbon deposits being blown out through the exhaust in a very short time. This allows perfect seatiniguof the valves, stops leakage and waste of alfords good compression, better starting, smooth running, and overcomes all the ill efl'ects' of carbon deposits.

. By the terms carbon, carbon solvent, etc as used in the specification and claims we intend to include the incrustations formed in internal combustion engines and commonly called carbon. These deposits are most likely, solid hydrocarbons having a pitch-like consistency, mixed with carbon or coke, the solvent having an action on the hydrocarbons thus loosening the coke mixed with the same.
